Question

Name the excretory organs in flatworms, earthworms, insects and snails.

Answer 1

Excretory organs

Excretory organs are the organs that help in the separation of wastes from the blood and subsequent elimination of these waste and harmful substances from the body.

The excretory organs in the asked organisms are as follows:

• Flatworms→ Flame cells (it is a hollow specialized cell that helps in the excretion of simple animals)
• Earthworms→ Nephridium (these are coiled tubules found in most invertebrates. It is found arranged segmentally in earthworms)
• Insect→ Malpighian tubules (these are tubular excretory organs, the junction of which directly open into the mid and hindgut.)
• Snails → Nephridium (these are coiled tubules found in most invertebrates)
